For the given time period, the price of BIOS tends towards a value in the vicinity of 6.02 (the mean) and 6.01 (the median).

Standard Deviation and Coefficient Of Variation are measures of dispersion. These can be used to measure the volatility (risk) of a security, and also to estimate the expected ranges of the price.

Assuming a normal distribution, we expect to see 68% of values within one
Standard Deviation of the mean (average), 95% of the values within two standard
deviations of the mean, and 99% of the values within three standard deviations
of the mean.

If the price of BIOS goes above 9.42 (mean + 1 standard deviation) or below 2.61 (mean - 1 standard deviation), then the reader is urged to investigate further for a possible buying or selling opportunity.

If the price of BIOS goes above 12.82 (mean + 2 standard deviations), then the reader is urged to investigate further as this would be an unusual event.
